The plastic sheet is aligned to the custom milled shape and heat and vacuum pressure applied. The 2D image is molded into the 3D shape of the custom milled shape.

A twin-sheet thermoforming process for the manufacture of vehicle headliners. In the process a first sheet and second sheet of SuperLite material are mounted onto respective frames. The frames transfer the sheets into an oven, where they are heated to a desired temperature using IR. The first sheet is combined with a cover-stock material using compression molding forming a covered first headliner part. The covered first headliner part is then transferred to a second mold station. The second sheet is heated and then transferred from the oven to the second mold station where it is vacuum-formed on the upper half mold, forming a second headliner part. The upper and lower mold halves are pressed together fusing and sealing the first and second headliner parts into a unified part. The unified part is then unloaded and trimmed as necessary forming a headliner. The SuperLite material used to form the headliner is a sheet of low pressure, thermoformable, thermoplastic composite comprised of polypropylene and long chopped glass fibers.

An improved mathematically modeled family of bellow fold patterns, useful for making bellows from stiff but foldable materials, which forms a corner of a bellow consisting of a series of several single inversion fold patterns, each having a characteristic design angle which is mathematically computed to provide a desired initial wall angle for the bellow and to minimize wall tilting over a predetermined extension angle range, thereby allowing low cost bellows to be made which can extend long distances while using a minimal amount of stiff but foldable material. In addition, each characteristic design angle can be computed to provide exactly zero tilting of the bellow walls at one or more non-zero extension lengths specified by a designer, thus allowing, unlike all other prior art folds, a structurally stiff, long extending bellow to be formed in an extended state using fast production techniques such as vacuum forming, blow molding or injection molding, while also allowing the bellow to be free of distortion in the compressed state.

A design of microchannels and a method for economic production of such microchannels. The new microchannel design comprises a thin thermoplastic film and a relatively thick substrate to form microchannels in-between. The microchannels are displaced on the film side. The method for fabricating such microchannels is a hybrid process combining compression, and blowing or vacuum forming to form microchannels between the film and the substrate. During the process, the film is placed on the top of the substrate. A mold or die with to-be-replicated microchannels clamps the film against the substrate. Either blow molding or vacuum forming is then carried out to deform the film and replicate the microchannels. Rapid heatable and coolable molds are preferred to soften the film and form bonds between the film and the substrate while short cycle time is maintained.
